    • An infrared seeker head for target tracking missiles has a main detector and an imaging optical system generating an image of a field of view on the main detector. The field of view contains a target such as an enemy aircraft. The missile is guided to the target in accordance with signals from the main detector. The target, if attacked by the missile, emits high-intensity laser radiation towards the missile as a counter-measure. This is to disturb the operation of the seeker head by dazzling or even destroying the main detector. The seeker head contains a device for defending against such disturbances. Various types of such defending devices are described. Incident light is deviated from the main detector. A second-quadrant-detector of reduced sensitivity guides the missile along the disturbing laser beam. Another embodiment uses attenuating optical elements in front of the main detector under the control of one or more second detectors.
    • 用于目标跟踪导弹的红外探测器头具有在主探测器上产生视场图像的主检测器和成像光学系统。 视野包含一个目标,如敌机。 导弹根据主探测器的信号被引导到目标。 目标,如果被导弹袭击,则向导弹发射高强度的激光辐射作为对抗措施。 这是为了通过眩目甚至摧毁主探测器来扰乱探头头部的操作。 引导者头部包含防止这种干扰的装置。 描述各种类型的这种防护装置。 入射光偏离主探测器。 灵敏度降低的二象限检测器沿着干扰激光束引导导弹。 另一实施例在一个或多个第二检测器的控制下使用在主检测器前面的衰减光学元件。
